[Date Roku] In a world where there are extremely few men, sperm is a precious resource. Part 2

In a world where men are vanishingly rare and sperm is a precious resource, one ordinary male student becomes the sole prize worshipped by a devoted harem of collar-wearing schoolgirls with heaving big breasts and plush, soft big asses desperate to be bred. A close trio of friends beg to take turns sharing him in a slick, trembling FFM threesome driven by yuri-tinged kisses and bisexual rivalry, while the poised, busty Student Council President Konami Nagase finds herself flustered and aching for the same creampie the next day. With uniforms slipping and bodies quivering to be filled and impregnated, every girl competes to prove she can take him deepest and waste not a single drop.
